Abstract:
A solid state lighting device comprising at least one first light emitter that emits non-saturated non-white light of a first color point, at least one second light emitter that emits saturated non-white light, and a controller configured to control a ratio of light emitted by the first emitter(s) and by the second light emitter(s) to provide non-white light of a second color point. Also, a solid state lighting device comprising at least one first light emitter that emits light within a first area or a second area on a Chromaticity Diagram, and at least one second light emitter, wherein output light is non-white and has a second color point. Also, methods of providing non-white light.
